ALBERT WASSBERG, OF COSCOB, CONNECTICUT.

HINGE-SEAT-MORTISING TOOL.

To all whom it may concern:

Be it known that I, ALBERT Wassnnno, a citizen of Sweden, residing at Coscob, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hinge Seat Mortising Tools, of which the following is a specification.

This invention relates to hinge seat mortising tools. Its object is to produce a plane especially adapted for finishing off and automatically gaging the depth of hinge-seats for doors, doorcasings and the like.

Another object is to produce an adjustable tool of this class that is simple, cheap to manufacture and positive and accurate in operation.

With the foregoing and other objects in view the invention consists in the combination of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawings which form a part of said specification and in which Figure 1 is a perspective of the tool and also of a piece of wood ready for operation by the tool. Fig. 2 is a plan of the tool in operation. Fig. 3 is a sectional side elevation taken on line 33 of Fig. 2. Fig. 4 is an enlarged view of the working parts shown in Fig. 3. Fig. 5 is a sectional detail of the adjusting mechanism taken on line 55 of Fig. 4. Fig. 6 is a transverse section in elevation taken on line 6-6 of Fig. 9.. Fig. 7 is an end. view of the finished product. Fig. 8 illustrates a spring return that may be used if desired.

Like reference characters indicate corresponding parts throughout the several views.

The numeral 1 indicates the stock of the tool which is secured to the handle 2 through the medium of set-screws 3 working through elongated apertures 4 in the sides of said stock thus affording means by which the handle may be raised or lowered vertically with relation to the stock. The extremities of the handle 2 are flattened as at 5 and one surface thereof serrated as at 6 and these flattened extremities are preferably held a short distance above the face 7 of the stock and extend from the forwardtermination 8 of said face out and over the work 9 upon which the serrations 6 permit a purchase thus bringing the said tool face in juxtaposition with one edge of the work.

10 is a lip running transversely of the face 7 along its forward edge disposed at right angles thereto and having a horizontally disposed aperture 11. therein flush with the face to permit the operation of the plane-iron 12 which rides over the said face and extends lengthwise thereof and out through a horizontal aperture in a lip 13 extending transversely of the rear edge of the face of the stock and connecting the side pieces thereof. Approximately the rear half of the plane iron is bifurcated and a slot 14 formed between the prongs thereof. This slot lies directly above and parallel with the slot 15 in, the face of the plane, the said slot lying between a pair of lips 16 made integral with the face 7 and formed on the under side thereof. Above the slot l t in the plane-iron and lying upon that iron is a small metallic piece 17 to which with a suitable washer between is secured the lever 18 of the tool by a threaded bolt 19 extending through an elongated aperture 20 in said handle and through the washer and piece 17 and on the lower end of which is secured a thumb nut 21 having its head adapted to ride upon the lips 16 of the slot 15. The forward extremity of lever 18 is pivoted as at to the face of the plane, thus permitting the movement of said lever in a manner to impart a reciprocating motion to the plane-iron which motion causes it to slide longitudinally over the face of the plane.

The forward lip 10 of the tool has made integral therewith a box-loop 23 that extends from the upper edge of this lip back over the face of the tool and is securely fastened to the lastnamed member at 2t. Upon this box-loop are located a pair of set-screws 25 that extend down through the loop and may rest upon or immediately above the planeiron. In operation when it is desired to se cure a hinge to a door or door-casing the work is first chiseled out somewhat in the manner shown in the work represented in Fig. 1 and indicated by 26. A recess the length of one wing of the hinge is roughly chiseled out, care being taken that the recess is made a depth less than the thickness of the hinge-wing in order that the same may be finished with the rabbet-plane. Grooves 27 are then chiseled out at right angles to the edge 28 of the work and the same is ready for the plane. The flattened extremities 5 of the handle 2 are placed upon the sent the appearance shown in Fig. 7. If it is desired to cut a deep incision in the work the handle 2 1s ralsed vertically by means of the setscrews 3, this will permit a deeper cut by the plane-iron as is readily seen; the screws may be tightened until they lightly touch the plane-iron and the screw 22 tightened. This will bring the plane-iron close down upon the face and as far as possible from the ends of the handle 2 thus insuring a deep incision in the work.

A modified form is shown in Fig. 8. A knob is secured to one end of the plane-iron and a screw 1 secured to the piece 17 extends through the slot la and has one end of a spring 1 fastened thereto, the other end of this spring engaging a pin 1 secured to the stock. When the plane-iron is forced forward by the knob the spring 1 will re- 25 turn the same to position again.

That I claim is In a hinge seat mortising tool, the combination with the stock, of apertured terminal lips extending transversely thereof, a boxloop made integral with one of the said terminal lips provided with a set-screw, a reciprocating plane-iron secured upon said stock, passing through said apertures and box loop and retained against said stock by the said set screw, a lever secured upon said plane-iron and pivoted to said stock and means adjustably secured to said stock for regulating the cut of said plane-iron.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of subscribing witnesses.
